Application ined october 24, 1923, serial No. 670,618, and irirranoo November. ii,v 1922.A f-

This invention relates to a monotype composing` machine, which perforates a strip' for controlling a. casting machine.

This device is adapted to allow of effecting compositions divided in4 columns, by ensuring the automatic justification in each column or section.

It is essentially.characterized by a drum carrying parallel screws on which are arranged adjustable nuts forming abutments for the external rack of the machine to.

ated according to the number of columns. At the end of the line, theindex engages,

with the smallbar, causes the disc to rotate and with it a distributor which sends air Linder a piston releasing the retaining pawl of the drum and permitting the return to Zero of the v latter and controlling also the return of the racks.

The invention is illustrated, but by way of example only, in the accompanying drawing in which:

` Figs. 1 and completing each other,showingthe whole of the new device. j. l Fig. 3 is `an elevation of the righthan'd end of the device asvconstructed. Y,

Fig. 3? is a similar view of' the left hand end ofthe device.

Fig, 4 is a plan view of the rilght hand end of the device. Figure 4a is a similar view of the lett hand end ofthe device.V

Figs. 5 and 6 are end `views of. the device.

Figs. 7 and 8 are two sections made respectively through lines A-A and A-B of Fig. 4. f Y I Figs. 9, 1() and 11 aredetail views.

`As shown in the drawing, the new device comprises a drum 1, Fig. 1, composedot1 two plates 2, 3 between which are arranged parallel screws 4 carrying nuts 5 acting as abutments. ment, as shown in Figs. 9 to 11; each of them is provided with Ya cap '6 jointed at 7; the

2 are two diagrammatic views i These nuts are of special arrange-V interior of this cap is screw threaded insuchi manner that, when the cap is turned down, it

comes in engagement with thethreads ofthe screws and that, when it is raised, the nutis released. It can be held closed by a socket 8 externally milled and. internally threaded, screwing on la' threaded bearing r5a formingthe end of the'nut and fitting on conicalportions of the nut and Vof its cap. The ends of the screws 4 fitted, in the plate 3, project on the'othery side andareeach provided with a slot in which can be engaged a screw driver 9, Figz, having a Amilled head 1 and-a returningspringll.; It` results from this arrangement that .for securf'j ing an abutment'atthe exact desired ,place,1-.

the socket 'isloosened untilfthe lcap rv6 is released; the latter is lifted and the` nut ois rapidly moved alongthe screw 4.y Then the socket 8 is.moved and screwed. The screw-V driver 9 is then pressed upon forl bringingl its end in contact with the head ofthe. screw 4 and cause the latter to turn according to `the necessary ext-entr for .completing the adjustment of the position of the nut.k i Y A hook 12 comes in contact with the abut-a,

ment 5; this hook in mounted on the -louter rack 13 on which it is pivoted;` a spring presses it against thescrews 4 of the; druml.

The plate 3 carries on. its periphery-a ratchet 14 which isin engagement withaff driving paivl 15 anda retaining pawll. The pawl15 can be actuated by the, rod 17 of a. piston 18 or `by hand .by 'means of. a milled f head 19. It can bereleased by a cam 2()v actuatedrby the rod 21 of apiston 22, or by a milled head 23 actuated byhand.'

VOn the shaft Vot' theratchet 14is rigidly mounted a bevelVV pinion 24 gearing j on another pinion 25 on the Vaxis of which is rigidly mounted an index 26. The latter jizz moves in front of a disc 27, loosely mounted on the axis, which comprises twelve sectors limited by notches 28. A small bar29 can be inserted in any kof theseno-tches.v For that purpose, it is rigid with ai Asleeve29,

capable of sliding on the axisofthe pinion 26 and pushed by a spring againstthedisc.

f The outer rack 13 ismoved in Vthe known manner by a pinion 8O rigid' withanother pinion 31 gearing with the inner rack 32 z.

Fig. 2.A This' distributor is provided with a duct 41 which can put in communication the two cylinders 42, 48 wherein move the pistons 18 and 22.

`The cylinder 42 communicates with an automatic valve 44 in relation with a two 28cwh-icli follows'thenumeral appearing on l juisted on the corresponding screw.

Y thatf'purpose, each screw is successively 1E'r'derf-toy 'effect"this'floperatiom the ratchet 2a;

lTheftcomposition can thenbe begun by Aforinlin'giiiV ea'ch 'section the I fraction ofV line i'vhj ae Aorftable. 1

w*By"pression" of the keys of the keyboard, the l"rack" 13 progresses towards the' Zerol of the scale E, .Fig-'11 When they digit 4 of the '('called 'the "e'ms77 scale)" is'V reached, a warns tiie'operator that he approaches theend lof the' line (in the first section) and @hmmag-aie justification.

One of the red keys of the lower row of the keyboard or the green key is then de pressed, one of the keys being indicated at 48, as above stated.

"'By AIdepressing this key, a passage is opened for the compressed air in the cylinder 35, this air then acting on the piston :18; 4The latter actuateslthe pawl 15 and the ratchet 14 rotates to the extent of a tooth. The "pawl 16 is withdrawn for allowing the ratchet to rotateV and `then takes Vback its position in which it'immobilizes the ratchet.

The piston 18moving in the cylinder' 42, uncovers an orifice 50,- so that the compressed air passing through `the valve 44 and lthe distributor 45 passes along a pipe 51, acts in the cylinder 86 and pushes back towards the right the piston 34 and the inner vrack f 32. The outer rack comes backtowards the left until it is stopped by the engagement of the hook 12 with the' new abutment 5 which, through the rotation of the drum having thus taken abutment.

The composition v of-lthe second section is immediately begun. The 'same operations as above areA repeated sections upto the last one, that of the right hand.- 1

The latter being composed, the index 26 owing to the successive `advances of the ratchet to which it isA connected by the pinions 24 and' 25, has come in Contact with the small bar 29 ,this small bar fitted in a notch 'of the dial is integral with the same.

Thus, the following rotation ofthe drum, at the end of the-"line constituted by the whole of the'fra'ctions of line of each column, has for effect to drive with th'e ratchet 14 and the index` 26, the small bar 29`and the'disc27. l

The gears 37, l38 then rotate the distributor 39 the opening41 ofwliich causes the two orifices 42L and y48a to' communicate. The compressed air then enters'in'theicylvin`der"43,behind, the piston 2,2. iIt 'enters also in thebranch'pipef52leading the'a'ir under the''.va'lves'44v and' 46 one'of whichcuts off the eXlt of the air frointhe cylinder42 Vand theother'the'v admission of' the airfto the cylinder 36,",thi`s aint-coming from thecylinder 53 wherein moves'a piston"54 'actuating the' drum 4'9unde`r'the actio'f of a' spring or of afco'unter'w'ei'ght. The piston 22moving in the cylinder 43, actuates the cam 20; the latter acts on a boss 2Oa of the 'fixed pawljtlius' releasing the drum 1. This drum, underthe action of aV returning spring', such as a barrel spring, indicated at 1(Fi'g. 1) comes back toits starting position. i This position is determined by an abutment-59. For' allowing mediante effectA l ay lcomplete revolution,` this abutmentvmoves place, hasreplaced the preceding of the*` fraction of linei in a helical groove 60 which is illustratedin Figs. 3 and 4.

The index 26 moves backward and comes in engagement with a. gudgeon 55 (Fig. 3) y which is fixed on the dial 27; this index ac-' tuates the said 'dial aswell as the distributor- 39, this cutting off the admission of comvpresed air to the cylinder 43 andv tothe Ybranch pipe 52.

The valve 44 is released `and comes back,

' under the action of its returning spring, to

lthe position illustrated; the air contained in? the cylinder 42 escapes'by passing through Vthe distributor 45 and enters in the cylinder 36 in which it actuates vthe piston 34 which brings back the rack to the starting The same actionsare repeated upon coim-` f u position of the following line and so on.

From the foregoing it will be seen that the new device comprises a mechanism Aof advance section by section and a mechanism for the automatic return to the first section,

' which do notrrequire any operation` during the work and, consequently, do not necessitate any attentionon the part oftheoperami.` Y

.During the rotation of the abutment-carrying drum coming back toits initial position, the rack d-oesvnot move. It is only after the drumhas come back to the st-arting pointthat the rack moves and that its hook l2 comes in engagement with the firstA It results therefrom' that this abutment. abutment can be, without inconvenience, very near the ratchet' 14. This would not be-the case ifl the above movements were simulf taneous. Incase the first section would be very narrow, the drum would not have time to effect its return before the hook is in position for engaging its abutment.

The new device has moreover, the main following advantages:

1.-It is possible, at any moment, to interrupt the tabular composition and to effect, for instance in case of urgency, the

composition of an ordinary text on any desired justification, without having to modify the adjustments of the automatic tabulator; the only operation to be effected for passing from the tabular composition to the ordinary composition, consists in turning in the suitable direction the two-way cock 45.

2,-The justifications of the. various columns can differ only of a. length as small rto' any of the justifications provided.; when several columns of a table have the same justification, it suffices therefore to adjust according to this justificationonly' one 'of the adjustable abutments of the tabulator;

`thus inY thecase of a work of smallimportance,A thejloss of" time caused by several i-dentical'adjustments is avoided and, morefications are available,` so that the number of the columns of a table can thus be very high.

iover, the abutments not used for other vjustiv 4.-Theindependence of vthe pneumatic control Vand of the direct control byhand allows of instantaneously bringingl backthe tabulator to-Zero (starting-point `of a line) incase of an erronnoticed in the composition of the line being composed.- f 5.-'l`he`indication of the number Vof the column ofnwhic-h the tabulator ensures .thel

automatic justification' is 4constantly' in sight of the operator in normal working position.

' 6.-Th e warning bell vindicating the end of the line and provided on the keyboard of thev machine on which is fitted the ltabulator,joperates foreach 4of kthe sections of line corresponding to acolumn of the' table.

Moreover, the vjustification drum which indicates, lat' theend of 'each' line, the total v length, of blanks which visto bedistributed and fthe numberfof variable spaces`V` between operates in proper time tions of the line.f

for each of the' n sec- (or four quadrates),lowerlimit of justification of the machine not` provided with thetabulator, provided theA whole of the section of one and the saine line comprises at least the seven letters, signs or spaces necessary for casting machine for sending to the galley the composed line. Thatisto say, by means of the tabulator, shorter lines can be made than heretofore. Y

VVThe above arrangements are, of course, given by way of example only; the forms,

7 .flh'e tabulator'allo'ws the justification y `of lines *having'a` length inferior'to 4 ems which itmust be distributed, automatically dimensions, materials used and all detail Y arrangements may be varied according to circumstances without departing thereby from the principle of the invention.
